Feed stop



and thus limits its advance movement. That portion of the wire lengthprojecting into the open space beyond the face of the die 38 is cut oiby a conventional cut-off mechanism (not shown). The length of theprojecting portion of the wire is determined by the position of the stoparm 2| relative to the die 30. One of such adjusted positions is shownby broken lines in Figure 2. This feed as a unit is moved out of itsoperative position, as shown in Figure 2 by rst removing the nut I9 andthen swinging it upon the pin le I4 to its non-operative positionillustrated by broken lines in Figure 2, a part thereof resting on astop pin 32, or other part. When in this latter position the space infront of the die block I I is open, unobstructed and accessible to theoperator for such work as is needful to be done therein.

In Figure 4 there is illustrated a stop plug 21, with a head 28 ofgreater height than that shown in Figure 2. This stop plug isadvantageous for workpieces of very short length, as the face of thehead can be brought closer to the die 30. 'I'he top face of the head 28may be flattened as at 33 to engage a shoulder on the stop arm 2l (Figs.2, 4 and 5) to hold the same against rotation.

Within the scope of the claims various changes and alterations may bemade in the design and construction of this improved feed stop withoutdeparting from the spirit thereof.

What is claimed is:

1. In combination with a die block through which material is fed; abacking plate having lugs thereon at a point above and in rear of theface of the die block; a base plate hinged to the lugs; a stop armthereon which is opposite the face of the die block when the stop meansis in its operative position; and a stop plug in the stop arm in thepath of the material.

2. Stop mechanism of the character described having a hinged basemember, a stop arm movably mounted thereon and projecting below the basemember; mechanism having means to adjustably hold said stop arm againstendwise movement having an intermeshing engagement with the stop arm formoving the same into its various positions, the stop arm having oneangular wall below the base member and of less width at the bottomthereof than near the base member.

3. Stop mechanism of the character described having a hinged basemember, a stop arm movably mounted thereon and projecting below the basemember; mechanism, as a screw, held against movement having -a threadedengagement with the stop arm for moving the same into its variousadjusted positions, the stop arm having one angular wall below the basemember and of less width below the base member; and a stop lug in thestop arm having a head exposed upon one side of the arm.

4. The combination with a die block or the like, through which materialis fed, of stop means for limiting the travel of the material, the stopmeans when in its feed limiting position being xed with respect to thedie block, and comprising in part a member hinged above the die blockand projecting beyond the face of the die block, and an arm on themember positioned in front of the face of the die block when the stopmeans is in its feed limiting position, and releasable means forsecuring the stop means with the arm in its feed limiting position, themounting of the stop means being such that it may be moved out of thespace in front of the die block and into a position thereabove.

5. In combination with a die block or the like, through which materialis fed, a member having one or more lugs above the plane of the materialas it moves through the die block, a base member hinged to the lugs andoverhanging the face of the die block, a stop member upon the basemember that projects therefrom in front of the face of the die block andin the path of the material, means for moving the stop member toward andaway from the die block with respect to the base member, and releasablemeans for securing the base member and whereby the stop member may bemoved out of the space in front of the die block and into a, positionthereabove.

6. In combination with a die block or the like, through which materialis fed, a member having one or more lugs above the plane of the materialas it moves through the die block, a base member hinged to the lugs andoverhanging the face of the die block, and in one position xed withrespect to the die block, a stop member slidable upon the base memberand projecting therefrom in front of the face of the die block in thepath of the material, and securing means to hold the stop member againstmovement on the base member.

7. In combination with a die block or the like, through which materialis fed, a backing plate in rear of the die block, a base plate hinged tothe backing plate and in one of its positions overhanging the face ofthe die block, means for securing the base plate in the last mentionedposition, and a stop arm depending from the base plate opposite the dieblock when in a position to limit the movement of material through thedie block, the connection between the base plate and backing plate beingsuch that when the securing means is released the base plate with thestop arm thereon may be moved, carrying the stop arm from its feedlimiting position to a position above and in rear of the face of the dieblock 8. In combination With a die block or the like, a support memberabove and in part overhanging the die block, stop means on the supportmember opposite the face of the die block for limiting the extent ofmovement of material beyond the face of the die block when the supportmember is in a fixed position, and means for mounting the support memberwhereby it may be moved upon its mounting and carry the stop means outof the space in front of the die block and above and in rear of the faceof the die block.

9. In combination with a die block or the like, a support member aboveand in part overhanging the die block, stop means having a slidingengagement with the overhanging portion of the support member andopposite the face of the die block for limiting the extent of movementof material beyond the die face when the support member is in a xedposition, and means for mounting the support whereby it may be movedupon its mounting and carry the stop means out of the path of movementof the material and above and in rear of the face of the die block.

10. In combination with a die block through which material is fed, abacking plate having lugs thereon at a point above and in rear of theface of the die block; a base plate vhinged to the lugs; a stop arm onthe base plate which is opposite the face of the die block when the stoparm is in its operative fixed position; and releasable means forsecuring the base plate and whereby the stop arm may be moved out of thespace in front of the die block and into a position thereabove.
